NGC 2477 in Puppis
Archives


 

Scope: Megrez II  f/4.1;  Location:  Blair Valley, Anza Borrego Desert  CA;  5 Feb. 2005; Camera: ToUcam SC3

Exposure: 24 x 24 sec  Luminance exposures with Baader IR Block Filter; 16 x 24,24,38 sec R,G,B 

Processing: All exposures captured  in K3CCDTools 2. Alignment and stacking was done with Registax 3 and saved as FITs. LRGB channels were co-registered in IRIS. Luminance and Color channels were scaled and rough color balanced in IRIS.  Due to the low horizon for this object from my location, the blue exposure was lengthened to compensate for atmospheric extinction on the shorter wavelength. Final LRGB combine was done in Photoshop using Luminance Layering (or LLRGB). Color balancing and final touches were done in Photoshop. SGBNR (PixInsight LE) was used to smooth background noise on the final result. Resized to approximately 800x600.

This image was a guided exposure. In this image NGC 2477 is a centrally dense open cluster that starts to look like a globular cluster. It is located in the constellation of Puppis. The bright star on the bottom edge is a magnitude 4.49 SAO198545 . Horizontal FOV is about 50'.
